FEED DEVICE FOR BOX-BLANK MATERIAL.

SPECIFICATION forming petrOf LetteISPabenit NO. 625,958, dated May 30, 1899.

Application filed February 4, 1899. Serial No. 704,478. (No model.)

To all whom, it may concern:

Beitknown that I, FREDERICK P. RosBAcK, a citizenof the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a new an d useful Improvement i n Feed Devices for Box-Blank Material, of which the following is a specification.

My invention relates to an improved feed device which I have devised more especially for use.(though I do not limit my inventionl thereto) in the manufacture of boxes formed from blanks composed of sheet-wood or veneer, carrying on' one side, at suitable intervals apart, parallel longitudinally-extending cleats anden the opposite side wires vcoincident with the cleats, the cleats, sheet, and wires being fastened together at intervals, as with staples driven through the sheet into the cleats and over the wires to straddle them.

The object of my invention is to provide an improved device for feeding the wooden sheets and cleats in their proper relative positions thereon and delivering them to a suitable machine for performing the stapling operation preparatory to the further operation of stepmiterin g the cleats, thereby to finish the blank and adapt it to be folded into box form.

Referring to the accompanying drawings, Figure l is a broken top plan view of my improved feed device; Fig. 2, vabroken longitudinal section taken at the line 2 on Fig.V l, viewed in the direction of the arrow and enlarged; Fig. 3, a section takenat the line 3 on Fig. 2 and viewed in the direction of the arrow; and Fig. 4. a broken section taken at the line et on Fig. 3, viewed in thedirection of the arrow and enlarged. v'

A is the frame, represented as composed of two parallel side bars a a, terminating at their ends in supporting-legs a' a', betweenw hich they are braced by cross-bars a2 and crossgirders as, shown as T-rails, extending'at intervals between the side bars. Y B B are the outer cleat-guides, formed, preferably, of angle-iron bars,jand B' is an intermediate cleat-guide formed, preferably, of a channel-iron bar, the number of cleatguides B to be provided being in accordance with the number of intermediate cleatsemployed' in ythe box-blank construction. Only one of the intermediate cleat-'guides is shown in the present device to adapt it for feeding box-blanks, provided with two outer cleats and one intermediate cleat. These cleatguides are supported to extend parallel with the sides of the frame across the girders as, and they are relatively adjustable. The guides B B are each fastened to a girder where it crosses the same by a curved clamp-bar b, bearing at its opposite ends, respectively, against the base of a cleat-guide and the under side of the top of the adjacent girder and fastened by a thumb-screw b', passing through it between its ends into the horizontal base of the guide B. To steady and positionvthe guide B, a clip b2, projecting from its base, engages with the opposite side of the head of the girder. By loosening the screws b the guides B may be-moved on their supports c3 to any desired distance apart, at which they are secured by tightening the screws. The intermediate cleat-guide B', the

top of which is below the upper edges of the guides B, has stems 't' depending from its base at intervals coinciding with the girders where they carry sliding sockets o', through which the stems pass vertically, being held therein by set-screws o2, and the sockets are fastened by thu rnb-screws o3, bearing against the 4under side of the top of the adjacent girder. On loosening the screws es the guide B may be moved to `any desired position relative to the outer guides B, where it is secu-red by tightening these screws.

At the inner side of each guide B it is supplemented by a bed-rail c, yieldingly supportedfrom underneath to bear against the innerY side of the guide and withits upper side normally on a level with the upper side of the base of the guide B. The yielding support for each rail c is provided at intervals thereon and comprises a bracket c', depending rigidly from the base of the guide B below the planes of the girders a?, a stem 02depending from the base of the bed-rail through the foot of said bracket and held by la nut c3, screwed on the lower projecting end of 'the stem, and a spring c4, confined around the stem between the bracket-foot and base of the rail. At intervals along the inner sides of the rails care fastened clamp-springs d to bear at their free ends normally against the inner sides of the guides B.

C and C are rotary shafts journaled inthe sides a of the frame, near its opposite ends, and carrying sprocket-wheels e c in pairs, about which extend endless chains c e', the whole forming an endless carrier. On the shaft C is a gear-wheelf, meshing with a pinionf' on a stub drive-shaft C2, suitablyjournaled, as shown in Fig. l, and carrying a beltpulley]u2 and a clutch f3, having its loose member engaged by one end of a bell-crank f4, the other end of which is connected with a rod f5, extending along the frame A to its front portion, where it.- is connected with an operating-handlef6, turning of which in one or the other direction ships' or unships the clutch. The pulleyf2 is belted to a line-shaft or the like and rotates constantly.

The more important feature of my improvement consists in a cleat-pusher D, carried by the endless chains c/ to advance the cleats, with the sheet-wood material upon them, uniformly and positively to the delivery end of the feed device. This cleat-pusher, as shown, involves the following-described construetion: On each chain c' is fastened, as shown of one of the chains, to ears ft thereon, a yokeshaped channel-bar g, and on the outer edges of these bar's is fastened, near their ends, to extend between the chains and bear on the guides IS, a plate g', beveled along itsforward and rear edges, as represented at x in Fig. 4. At intervals across the base of the plate g extend push-bars g2, in n umber corresponding with the number of cleat-guides, with which they should coincide. Each push-bar terminates at its forward end in an upwardprojecting head g3, containing at its angle of junction with the body of the bar a beveled groove fr to receive and confine the correspondingly-beveled forward edge of the plate g'. The rear beveled edge of the plate fits into correspondiugly-beveled grooves x2, provided in bearings g4, one of which is provided at the rear end of each pusher-bar and through which a bolt g5 is passed into the respective bar g2, as shown in Fig. 4. Thus the pusher-bars are confined or clamped between the heads g3 and bearings g4 upon the base of the plate g', and they may be readily moved to adjust them into respective desired coincidence with the cleat-guides B B upon loosening the bolts g5.

Means are also provided to hold down against the cleats and prevent buckling or disarran gement of the sheet material imposed thereon, as hereinafter described. The means referred to are shown as involving the following-described construction; In bearings h 7L', fastened in pairs to the side bars a of the frame A, at opposite ysides of its transverse center, are supported rigidly rods h 7L. On these rods are slidingly supported at their sleeve portions i2 and fastened in their adjusted posit-ions by set-screws 3, passing through the sleeve portions, vertical socketpieces i, through which depend threaded stems t", shown sustained by wing-nuts i on their upper projecting ends and held to resist upward rise, preferably, by nuts i5 on their lower projecting portions. Each pair of the stems t" carries a presser-bar k, in the form of a thin metal bar having its end portions rounded at their lower edges, as shown in Fig. 2, the bar extending parallel with and adjacent to a cleat-guide B.

The guides B B may terminatejust beyond the shaft C or may there be only interrupted, as represented in Fig. l, to permit the passage of the pusher device toward its return movement in the travel of the endless chains.

The operation is as follows: 'Vith the adjustable parts arranged according to requirement, cleats X are inserted cndwise from the end of the feed device to which the shaft C is adjacent upon the bed-rails c, between the clamping-springs d and adjacent sides of the guides I3, and a cleat is similarly inserted int-o the intermediate channel-guide B', and sheets Y of veneer are imposed upon the cleats with their edges confined between the vertical sides of the outer guides B. The cleats and sheets are placed in position, as described, while the machine is at rest. In the inserted positions of the cleats their rear ends are in the paths of the pusher-bars g2 of the cleat-pusherD, whereby when the machine is started, by throwing in the clutch f3 to cause the shaft C to be turned by the constantly-rotating pulley f2 the travel of the chains carries the cleatpusher against the cleats and advances them to the delivery end of the feed device and with them the sheets Y, abutting one against the other. The sheets are held by the presser-bars 7.: in sufficient frictional contact with the cleats, owing to the extent of the rough contacting-surfaces of the cleats and sheets, to be carried by the movement of the cleats, this frictional engagement not being lessened by the contact with the sheets of the bearing-bars k, because their lower contact edges are very narrow and are or become by use polished to a degree which avoids any friction resistance from them against the sheets.

That I claim as new, and desire to secure by Letters Patent, is
